Summary:
The EdenFS codebase uses folly/logging/xlog to log, but we were still relying
on glog for the various CHECK macros. Since xlog also contains equivalent CHECK
macros, let's just rely on them instead.
This is mostly codemodded + arc lint + various fixes to get it compile.

Summary:
This commit introduces a new process spawning class derived
from the ChildProcess class in the watchman codebase.
`SpawnedProcess` is similar to folly::Subprocess but is designed around the
idea that we will use a system provided spawning API to start a process, rather
than assuming the use of `fork`.
`fork` is to be avoided because it can be expensive for processes with large
address spaces and also because it interacts poorly with threads on macOS. In
particular, we see the objC runtime terminating our process in some scenarios
where fork and threads are mixed.
There are some important differences from `folly::Subprocess` and that means
that some assumptions and uses need to be altered slightly from their prior
workings. For example, detaching a SpawnedProcess moves the responsibility of
waiting on the child to a periodic task as there is no way to detach via
posix_spawn without also using fork.
On the plus side, this commit allows unifying spawning between posix and
windows systems, which simplifies the code!

Summary: Introduce a new ScribeLogger class that spawns and maintains a process. Log messages are newline-delimited and written to the process's stdin. If the process stops responding or responds too slowly, log messages are dropped.
